155816 divided by 78 
We're looking to find how many times 78 goes into 155816.

Let's proceed to step 1:
78 goes into 1 0 times with a remainder of 1.
The number 0 becomes the next digit in our result. 
Result so far: 0.0
Subtract 0 from 1 to get 1.
Grab the next digit (5) from the dividend, add it to 1, then carry on: 15 / 78

Going ahead to step 2:
The number 78 fits into 15 0 times, leaving a remainder of 15.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 15 leaves us with 15.
Fetch the next digit (5) from the dividend, attach it to 15 and continue: 155 / 78

Step 3:
The number 78 fits into 155 1 times, leaving a remainder of 77.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 78 from 155 leaves us with 77.
Include the next digit (8) from the dividend after 77, then repeat: 778 / 78

Going ahead to step 4:
The number 78 fits into 778 9 times, leaving a remainder of 76.
The number 9 becomes the next digit in our result. 
Result so far: 19.0
If we subtract 702 from 778, we get 76.
Grab the next digit (1) from the dividend, add it to 76, then carry on: 761 / 78

On to step 5:
761 divided by 78 is 9 with a remainder of 59.
Write down 9 as next digit of the result. 
Result so far: 199.0
Subtracting 702 from 761 leaves us with 59.
Bring next digit (6) of the dividend behind the 59 and repeat the process: 596 / 78

Step 6:
If we divide 596 by 78, we get 7 and a remainder of 50.
Put 7 as the next digit of the answer. 
Result so far: 1997.0
Deduct 546 from 596 and we're left with 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Going ahead to step 7:
If we divide 500 by 78, we get 6 and a remainder of 32.
Record the quotient 6 as the next digit in the result. 
Result so far: 1997.6
The remainder is 32 after subtracting 468 from 500.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 8:
If we divide 320 by 78, we get 4 and a remainder of 8.
The number 4 becomes the next digit in our result. 
Result so far: 1997.64
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Step 9:
If we divide 80 by 78, we get 1 and a remainder of 2.
Write down 1 as next digit of the result. 
Result so far: 1997.641
Deduct 78 from 80 and we're left with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

On to step 10:
The number 78 fits into 20 0 times, leaving a remainder of 20.
The number 0 becomes the next digit in our result. 
Result so far: 1997.641
Subtract 0 from 20 to get 20.
Since there are no more digits in the dividend, we add a zero to the remainder making it 200, and continue the process.

Going ahead to step 11:
200 divided by 78 is 2 with a remainder of 44.
Put 2 as the next digit of the answer. 
Result so far: 1997.64102
If we take 156 away from 200, we end up with 44.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 12:
If we divide 440 by 78, we get 5 and a remainder of 50.
Write down 5 as next digit of the result. 
Result so far: 1997.641025
Subtract 390 from 440 to get 50.
Since there are no more digits in the dividend, we add a zero to the remainder making it 500, and continue the process.

Advancing to step 13:
500 divided by 78 is 6 with a remainder of 32.
The next digit of our result is 6. 
Result so far: 1997.6410256
Subtracting 468 from 500 leaves us with 32.
Since there are no more digits in the dividend, we add a zero to the remainder making it 320, and continue the process.

Let's proceed to step 14:
When dividing 320 by 78, we get 4 with a remainder of 8.
Record the quotient 4 as the next digit in the result. 
Result so far: 1997.64102564
Subtract 312 from 320 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The final outcome is 1997.64102564, with a leftover of 8e-09.
